Game APK? What is’t mean?

An Android Package Kit (APK for short) is the package file format used by the Android operating system for distribution and installation of mobile apps. Just like Windows (PC) systems use an .exe file for installing software, the APK does the same for Android.

Now, you can understand that game apk are games exclusively for the Android operating system. Game apk are games not downloaded directly from Google Play but downloaded via another website. But this may be poses a risk if hackers intentionally create malicious code and attach it to the apk file you download.
